Product Details

Yusion Industrial supplies Rock Bit Balls for drill bits.Drill bits is the important tool in oil drilling,its performance will directly affect the quality of the drilling,the drilling efficiency and drilling costs.Therefore,drill bits have strict requirements on rockbit balls.

Yusion S-2 Tool(Rockbit) Ball are made from S-2 tool steel as per ASTM A681 and specially heat treated to provide excellent hardness and wear resistance combined with toughness and impact resistance to survive extreme shock loads found in the drilling industry.The balls we produced are ranging from 6.35mm to 63.5mm with grade from G40 to G200.The ball surface has a smooth ground anad polished finish.They provide good wear characteristic and good services in withstanding the abrasion of pulverized rock and mud slurries.
